Plans show that the 5,577 feet-high Sky Mile Tower will stand in Tokyo Bay with a cluster of islands at its feet, dwarfing everything else on the city’s already soaring skyline.

The tower will feature a hexagonal design, which was found to be the most wind-resistant shape, with six interconnected “building legs” forming a slotted, tapered structure that should withstand imposing winds.

It will offer multi-level open-air sky decks at every 320 metres and shared public facilities including shops, restaurants, hotels, libraries, gyms and health clinics.

Up to 55,000 residents will be housed, with lifts running vertically between the top and bottom of each of the building’s five “residential zones” and horizontally within each zone, forming a looping lift system, providing service to and from the different sky lobbies. More info and photos
